CHURN.

SPECIFICATION forming part of Letters latent No. 519,746, dated May 15,1894.

Application filed December 26,1893. Serial No. 494,790. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM H. THOMAS, a citizen of the United States,residing at Taylorsburg, in the county of Henry and State of Virginia,have invented a new and useful Churn, of which the following is aspecification.

The invention relates to improvements in churns.

The object of the present invention is to improve the construction ofchurns, and to provide one which will be simple and comparativelyinexpensive in construction, and which will be capable of efiecting arapid production of butter, and in which any kind of churn body orreceptacle may be employed.

The invention consists in the construction and novel combination andarrangement of parts hereinafter fully described, illustrated in theaccompanying drawings, and pointed out in the claims hereto appended.

In the drawings-Figure 1 is a perspective View of a churn constructed inaccordance with this invention. Fig. 2 is a detail perspective view ofthe spring and bar for securing the churn cover in place. Fig. 3 is adetail sectional view of one of the adjustable bearmgs.

Like numerals of reference indicate corresponding parts in all thefigures of the drawings.

1 designates a frame, comprising a base or platform 2, a top 3 and legs4;, which support the top and which are slightly inwardly and upwardlyinclined. The base or platform 2 is provided with a socket 5, which ispreferably circular, and in which is seated a churn body or receptacle6. The socket 5 consists of a vertical flange provided at intervals withfeet 7, which are secured to the frame.

The churn body is provided with a cover 8 composed of two separablesections, which are provided with opposite recesses to form a dasher rodopening, and which have contiguous extensions 9 forming handles. Thecover is secured on the churn body or receptacle during the operation ofthe churn by means of aspiral spring 10, and a removable bar 11 havingits ends 12 recessed and engaging correspondingly recessed blocks 13 ofthe frame. The spiral spring 10, which bears against the cover, andwhich is interposed between the same and the removable bar, and whichholds the latter in position, is provided at its outer side with avertical opening 14 forming an entrance to its interior for a dasher rod15. The opening 14 is formed by a series of segmental or incompleteloops 16, constructed of a single piece of resilient wire, which is bentto form an incomplete or segmental loop and is then bent backward andreturned to form another loop and so on leaving the ends separated toform openings one above another to provide the vertical entranceopening. This construction greatly facilities the removal of the coverand the replacement of the same. The upper end of the spring is securedto the removable bar 11, which is provided with a curved recessregistering with the interior of the spring.

The dasher rod 15 has its upperend arranged in and guided by a block 16;it is provided near its upper end with a series of adjustingperforations, any one of which is adapted to receive the upper end of apitman 17, which has its lower end detachably and adj ustably secured toa crank arm 18. The crank arm 18 is provided with a series ofperforations, and

is rotated by a shaft 19, with which it may be formed integral or beotherwise fixed thereto. By these adjustments the reciprocation of thedasher at the lower end of the dasher rod may be readily regulated tosuit any receptacle, and the contents thereof. The guide block 16 issupported by three upwardly and inwardly inclined rods 20, 21, and 22,which have their upper ends secured to the block 16, and their lowerends attached to the top of the frame at the ends thereof and at oneside adjacent to the shaft 19. The top of the frame is provided with twolongitudinal openings, in one of which is mounted a fly wheel 23, and inthe other rotates a drive wheel 24, mounted on a shaft 25 and connectedby a belt 26 with a pulley 27 of the shaftl9. The shaft 25 is providedwith a crank handle by means of which the churn is operated.

In order that the belt may be held at the proper tension the shaft 25 isjournaled in adjustable bearings 28, which have shanks 29; the shanksare arranged in openings of the frame, and the bearings are secured atthe desired adjustment by wedges 30.

It will be readily apparent that the churn is simple and comparativelyinexpensive in construction, that it is adapted to receive various sizesof receptacles to serve as a churn body, and to regulate its stroke toagree with such receptacle and the contents thereof, and that it iscapable of rapidly producing butter.

Changes in the form, proportion, and the minor details of constructionmay be resorted to without departing from the principle or sacrificingany of the advantages of this invention.

What I claim is 1. In a churn, the combination of a frame, a churn bodyprovided with a removable cover, a dasher rod passing through the cover,and a spring connected with the frame and bearing against the cover andsecuring the same in place, and provided at one side with a verticalopening forming an entrance to its interior and enabling it to bereadily placed on and removed from the cover without removin g thedasher rod, substantially as described.

2. In a churn, the combination of a frame, a churn body mounted thereonand provided with a removable cover, a dasher rod passing through thecover, and a spring bearing against the cover and connected with theframe, and provided at one side with a vertical opening forming anentrance to its interior, said spring being composed of a series ofsegmental loops, having their ends separated, and constructed of asingle piece of resilient material and having their openings or thespaces between their ends arranged one above another, substantially asand for the purpose described.

3. In a churn, the combination of a frame provided with recessed blocksarranged at opposite ends thereof, a socket arranged at the bottom ofthe frame and consisting of a vertical flange, a churn body mounted inthe socket and provided with a removable cover, a dasher rod passingthrough the cover, a removable bar having recessed ends engaging saidblocks, and a spiral spring secured to the bar and bearing against thecover and provided with a vertical opening forming an entrance to itsinterior, substantially as described.

In testimony that I claim the foregoing as my own Ihave hereto affixedmy signature in the presence of two witnesses.

WILLIAM H. THOMAS.
